Hi Vittali,
as you can expose SAP BW Infoprovider to the SAP HANA repository, you can build models in SAP HANA that use data from SAP BW and eventually process it via PAL or R or any other feature in SAP HANA.
These models can be consumed by SAP Visual Intelligence (or any other visualization tool for that matter).
The other way around, consuming SAP HANA models in SAP BW is also possible e.g. via Virtual Providers.
However, there is no direct HANA/PAL object in SAP BW.
